Smart/intelligence anons, can you please share your secret...

just watched a documentary about sex
youtube.com/watch?v=JakdRczkmNo

it seems females like men with big brains... I don't have a big brain, my head is always empty, I am not creative, witty, or funny... I will die alone if I can't improve my mental capabilities...

literature art and music
physical activity
genuine interest in people and things
constantly hone your critical thinking skills
question everything and fact check

Bro some people are smart and some people aren't. You can't make yourself smart.
